The last 6 years I have been using 2 Beretta 682's as my primary turkey guns. I do like the idea of having two different chokes if you want. I normaly use a X-full on the top bottom barrel and a skeet on the bottom just in case a gobbler jumps on top of me.
In the past I have used Remington 870's and 1100's and a very tight patterning Winchester 1897 pump. They all have taken their share of gobblers.
